Application filed November 2, 1925. 'Serial lo. 'I A This invention relates generally to doveltail constructions, particularly designedor j with the 'doors of vehicle bodies and the 1 e. f

One of the essential Objects of the invention is to rovide al simple form of dovetailv thatV is adjustablewithout interfering with.

the usual trimming material of the vehicle' y body to compensate for any irregularities such as s agging'resultingjfrom the mounting of the door; to prevent rattling audio take care of wear of the engaged parts while in use. l Another object is to provide al dovetail of vthis type that can bemanufactured and vassembled ata comparatively lowcost.

With the above and other objects in view, the invention resides in certain novel teatures of construction, combinations and arrangements of jlrts as will'be more 'fully pointed out in t e appended claims.

In the accompanying drawing: Figure 1 is a fragmentary side elevation of a door pillar with a dovetail member embodying my invention attached thereto.

Fi re 2 is a vertical sectipnal View taken on the line 2--2 of Figure 1. Figure 3is across sectional the lme 3-3 of Figure 2. 3 Referring now to the drawing, the" numeral` 1 designates a door pillar having a depressed portion 2 in the outer wall 3 thereof for receiving the dovetailmember 4. As shown, this member 4 has a fiat` base 5 and view taken on the laterally projecting horizontally disposed p' tongue 6 that is adapted to engage a suitable keeper (not shownlon the door jamb when the door is closed.

In order that the dovetail will lcompensate 4 for irregularities such as sagging, resulting from mountin ofthe engage parts, the member 4 is preferably adjustable longitudinally of thev vertical door pillar 1. As shown, spaced elongated slots 7 are provided in the depressed portion 2 of the pillar Jfor receiving suitable securin elements such as the screws 8 which extend' reely through the base 5 of the dovetail member and threadedly engage a fiat attaching plate 9 located on the inner side ofthe pillar 1. Thus, with this construction, the dovetai'l member 4 and plate '9 are caable of moving as a unit longitudinally of the pillar tothe proper position, whereupon the door and 'also for wear .having a depressed portion,

the screws 8- may be adjusted to clamp the base I5 andfplate 9 firmly against opposite vsides of the depressed portion 2. l To prevent any accidental displacement of the dovetail member 4,when in adjusted position, the base 5 of said member is preferably .provided with suitable transversely extending serrations 10 which are engageable .with similar serrations l1 on the adjacent.

-outer'face of the depressed portion 2 'of the door pillar.

Located upon the inner face of the depressedvportion 2 .of the pillar isa sheet metal housing 12 for the attaching plate 9. As shown, this yhousing 12 is preferably a closed channel having the lateral ianges 13 and 14 respectively vwhich arel preferably Welded to the'adj acent portions of the pillar. Thus, with this construction, the attaching plate 9 will alwaysbe held in rear of the depressed portion 2, hence the screws 8 may be loosened or removed entirely to adjust or replace the dovetail member without losing the attaching plate 9 and may subsequently be readily adjusted in the attaching plate to hold the dove tail member. As a result of this'construction it will not be necessary to remove or replace any of the usual trimming material to gain access to the inner side of the pillar for the purpose of holding the attaching plate during any of the operations mentioned above.

While it is believed that from the fore- -going description, the nature and advantage of my'invention will be readily apparent, I desire tov have it understood that I do not limit myself to what is herein shown and described and that such changes may be resort- `edvto when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. The combination with a door pillar in a wall thereof, of a dovetail member in said depressed portion and an adjustable connection between said member and 'pillar permitting said member to be adjusted lengthwise of said pillar without being removed therefrom.

2. The combination with a door pillar having a depression'therein, of a dovetail member having a flat-base seated in said depression, an attaching plate o-n the back of said depression, and securing means for the dovetail member extending freely through the base, movable lengthwise of the depression and threadedly engaging said plate.

3. In combination, a dovetailv having a substantially flat base and a laterallyl projecting tongue disposed at substantially right angles to the base, an attaching plate substantially parallel to the base, adjustable securing elements for the dovetail extending freely through the base and threadedly engaging said plate, and a supporting-member disposed betweenthe dovetail and plate and having elongated slots receiving the securing elements aforesaid, the connection between said dovetail, supporting member and plate being such that the dovetail and attaching plate may be adjusted as a unit upon the support Without being removed from said supporting member and Without interfering With any other part that may be associated with said support.

4. In combination, an upright member havinga substantially flat portion provided with an elongated 4longitudinally extending slot, a dovetail having a base upon the outer side of said'flat portion and having a laterall projecting tongue disposed at substantia ly right angles to said base, an attaching plate u on the inner side of said lat portion, an an adjustable connection between said base and plate including an element extending freely through said base and slot and threadedly engaging said plate.

5. The combination with a pillar having an upri ht metal Wall, of a dovetail. assembly carrled thereby and adjustable as a unit relative thereto without being removed therefrom, said assembly including a dovetail member upon one side of'said Wall, a member u on the opposite side of said Wall, and an a justable connection between said lirst and second mentioned members normally holding said assembly in position upon said Wall but adapted upon being adjusted to permit said assembly to be bodily adjusted relative to said Wall as aforesaid, said connection including an element extendin freely through one of said members and t readedly engaging the other of said members. In testimony whereof I aiilx my signature.
